1 Advanced Triple PWM and Dual Linear Power Controller for Portable Applications The IPM6220A provides a highly integrated power control and protection solution for five output voltages required in highperformance notebook PC applications.
The IC integrates three fixed frequency pulse-width-modulation (PWM) controllers and two linear regulators along with monitoring and protection circuitry into a single 24 lead SSOP package.
The two PWM controllers that regulate the system main 5V and 3.
3V voltages are implemented with synchronousrectified buck converters.
Synchronous rectification and hysteretic operation at light loads contribute to high efficiency over a wide range of input voltage and load variation.
Efficiency is further enhanced by using the lower MOSFET’s rDS(ON) as the current sense element.
Input voltage feedforward ramp m...
